LOCK.

Application filed April is, 1922. Serial No. 554,526.

T 0 all whom it may concern Be it known that I, OLIVER E. GIBSON, a citizen of the United States, residing at Mechanicsburg, in the county of Cumberland and State of Pennsylvania, have in vented certain new and useful Improvements in Locks, of which the following 1s a specification,

This invention relates to a lock and more particularly to such a device comprising a sliding bolt and an operating element therefor, which may be reversed in its relative position to the casing and bolt, enabling it to be used as either an inside or outside lock for aclosure member. The adaptation of the invention selected for the purpose of illustration is its use in connection with a sidewalk door, in which the weight of the operating plate is suflicient to cause the bolt to be projected from the lock casing and in which the said operating plate is provided with an opening making the plate useful as a handle for lifting the door, and wherein the reversibility of the parts enables the edge of the plate to be set flush with the up per outer face of the door or to be located entirely below the door; in its flush position it may be lifted by the application of the fingers of the hand provided suitable means, such as bevelled grooves, are provided in the face of the door for that purpose.

The object of the invention is the production of a lock for a door capable of several uses without change of construction but merely upon the reversal of the relative position of the parts. A further object of the invention is the provision of such a lock which may be used as either an inside or outside look. A still further object is the proing edges of a pair of leaves of a sidewalk door showing the bolt of the lock mounted upon one leaf and engaged under the trussed gutter carried andprojecting fromthe edge of the companion leaf,

Figure 2 is a plan of a section of the'leaf carrying the lock showing the plate edge and linger grooves therein;

Figure 3 is an elevation of the operating plate and associated parts with the cover' plate of the lock casing removed;

Figure 4 is a section taken on the line l-4 of Figure 2, and

Figure 5 is a view similar to Figure 3 showing the operating plate reversed for use with a closure leaf having no opening for the projection of the plate'above the surface thereof.

The form of the invention shown and described is but one of many in which-the invention may be embodied, and it will be appreclated that changes in details may be made in the construction of the parts, as'for instance, the casing may be cast in one block. It is also obvious that the application to which the lock is shown as placed is but one of its numerous applications. Therefore the embodiment shown and described is to be consldered as merely indicative of the inventlon, but nevertheless has been found tobe practical in construction and efficient in operation.

The closure leaves are designated by the numerals 10 and 11, the trussed gutter by 12, lock casing by 13, sliding bolt by 14:and operating plate by 15. These parts will now be described in detail and their individual functions set forth, after which a recital of their conjoint operation will be given.

The casing 13 is secured to theunder face of the closure leaflO by the provision of securing lugs 16 of any suitable shape, preferably as shown of angle formation, which fit within the ends of suitable reinforcing elements 17 attached to the closure leaf at both sides of the lock casing. Rivets 18 are employed to secure the lugs and the reinforcing elements to the closure leaf, It will be understood that the casing 13 may be made in a single casting, but as shown in cover plate 19.

The casing is provided with a vertical opening for the reception of an operating plate and with a horizontally disposed opening for the reception of the bolt 1e. In the plate is provided the hand opening 20 and the angle slot 21. Secured in a suitably threaded aperture in the plate .is the headed screw 22, the head 23 of which lies, when the parts are assembled, in the angle slot 21. In the plate 15 there is also provided an aperture 24: inwhich is inserted the yoke25 of a lock 26.

Referring now to Figures 1 to 4, it will be seen that the closure leaf 10 is provided with a slot 27 in which the upper end of the plate 15 lies with its upper edge flush with the outer surface of the closure leaf when the bolt is in latched position. Along this slot and to both sides of the edge of the plate are provided bevelled grooves 28, but these need not be provided unless it is desired that the operating plate should be raised from the outside of the closure.

'From an inspection of Figures 3 and 5 it will be seen that the relative position of i the plate 15 with respect to the casing and bolt may be changed. I shall first describe the use of the lock in connection with the position of the plate as shown in Figures 3 and 4. By gripping the edge of the plate 15 which lies between the beveled grooves 28 between the thumb and forefinger, the

' plate may be raised without actuating the bolt 14 until the screw head 23 reaches the bend 29 of the slot 21, at which time the hand slot 20 will be sufficiently above the upper face of the closure leaf to permit the passage of all the fingers of the hand therethrough when the bar 30 will constitute a lifting handle for the unlatching and raising of the closure leaf. A continued raising of the plate 15 will cause the screw head to travel along the inclined portion of the slot 21 and retract the bolt 14. WVhen the 1 screwheadoccupies the lower end of the inclined portion of the slot, the plate will be held against further movement within the casing and the closure leaf can be lifted.

When the closure leaf is swung over to an inclined open position, as is usual in sidewalk doors, the weight of the plate 15 and bolt 14: will maintain the handhold projecting from the face of the leaf, and when it is desired to lower the closure, it is only necessary to grasp the said handhold, lift the leaf to a vertical position and drop it in place over its opening. When it has reached its closed position resting with its edge supported by the gutter carried by the companion leaf it is only necessary to remove the hand from the opening 20 permitting the plate 15 to drop when the bolt 14 will be projected under the edge of the gutter 12 due to the weight of the plate and the reverse movement of the screw head 23 in the angle slot 21. The first portion of said dropping movement accomplishes the sliding of the bolt while the remainder brlngs the top edge of the plate flush with the upper surface of the closure leaf, from which position it cannot be again lifted unless the surface of the closureleaf-is provided with the beveled grooves 28 or similar means to permit of the gripping of the top of the plate between the fingers. In the final position of the parts the yoke of a padlock may be passed through the aperture 24 when the door will be effectually locked against open- If it is desired that the look at this invention be used with a closure having no slot corresponding to the slot 27 of Figure 2, the screw 22 is removed from the casing through an opening 31 in the side of the casing or in the cover 19, as the case may be, when plate 15 is released from the casing and reinserted therein in the position shown in Figure 5 and the screw 22 replaced at the time the aperture in the bolt is brought into alignment with the hole 31 and the slot 21. In this position of the parts the lock is adapted to be actuated only from the inside of the door. In such actuation the hand grasps the bar 30 and pushes it upward. The preliminary movement causes the sliding of the bolt from its projected position, thereby releasing the closure leaf. Further upward pressure immediately brings the upper edge of the plate in contact With the under surface of the closure leaf, which can then be lifted to its inclined open position where the weight of the plate will cause the bolt to remain retracted. It will be seen that in closing the door, the bolt will be held retracted as long as the leaf is supported upon the plate 15, but as soon as the door has been closed and the plate permitted to drop, the bolt will be projected and the door automatically locked. Since there is no means for lifting the same from the outside, as in the form of Figures 1 to 1, there will be no necessity for the provision of a padlock opening.

It will be appreciated that in my invention I have provided a lock capable without change for use asan inside or an outside lock for a door as well as a convenient binding door leaves and also eliminate any rattle that may occur when the leaves are in closed position.

Having described my invention, what I claim' as new and desire to secure by Letters Patent is:

1. In combination with a closure having an opening therein, of a lock casing secured to one face thereof, a bolt in said casing, and an operating member for said bolt adapted to be reversed in its position relative to said bolt and casing to enable it to be grasped from either face of the closure, providing either an inside or an outside lock for said closure.

2. In combination with a closure, of a lock casing secured to one face thereof, a bolt in said casing adapted to be projected therefrom into locking position, a sliding plate in said casing having an opening therein to provide a handhold by means of which said closure may be lifted and lowered, connections between said bolt and plate whereby the movement of saidbolt is controlled, said plate being reversible in its relation to said casing and bolt causing the handhold to be made available for opening and closing a door by the use of said handhold from either the outside or the inside and to operate said bolt in either of its said uses.

3. In combination with a closure having a slot in its surface, of a lock casing having an opening therethrough in alignment with said slot and a second opening therethrough at an angle to said first opening, a slidin bolt in said casing adapted to be projected into locking position from said casing, an operating plate in said first opening, and connections between said plate and bolt, the upper edge of said plate lying flush with the upper surface of said closure and fitting the opening therein.

4. In combination with a closure having a slot in its surface, of a lock casing having an opening therethrough in alignment with said slot and a second opening therethrough disposed at a right angle to said first opening,

a bolt carrying a headed screw, an operating plate lying in said first opening with its edge flush with the upper surface of said closure and having a slot in which the head of said screw is adapted to travel, whereby upon the lifting of said plate the bolt is retracted from its projected position.

5. In combination with a closure having a a slot in its surface, a casing carried by said closure and having an opening there- .through in alignment with said slot, a bolt 6. In combination with a closure having a slot in its surface, a casing carried by said closure and having an opening therethrough in alignment with said slot, a bolt in said casing, an operating plate for said bolt lying in said opening and slot with its upper edge flush with the upper surface of said closure and having an elongated slot in its upper portion defining a handhold for the lifting of said plate to retract said bolt, said closure surface being recessed to provide means whereby said plate may be grasped by the fingers and raised sufficiently to permit the hand to be passed into said handhold.

7. In combination with a closure having a slot in its surface, a casing carried by said closure and having an opening therethrough in alignment with said slot, a bolt in said casing carrying a headed screw, an operating plate for said bolt lying in said opening and slot with its upper edge flush wit-h the upper surface of said closure and having a handhold in its upper portion and an angle slot in which the head of said screw travels, whereby a preliminary movement of said plate will project the handhold above the closure surface and continued movement thereof will retract said bolt and finally the closure may be lifted.

In testimony whereof I afliX my signature.
